Description

Masterpiece 2-Bedroom Carroll Gardens Condo

Located on Union Street between Smith and Hoyt Streets, this perfectly located and spacious 2-bedroom condominium with separate living and dining rooms is sure to check all of the boxes. This fully renovated, 1,025 square foot apartment includes two spacious bedrooms, a modern kitchen, and for those who love to entertain, the rarity of separate living and dining rooms.

Modern conveniences abound. Enjoy the comforts of central (split) air conditioning, acoustically isolating floating ceilings, and an in-unit washer & dryer. Classical styling is dashed throughout with solid oak flooring, original moldings and enframements, and designer light fixtures.

Situated on the third floor of this walk-up building, the apartment has an entry hall leading to the open kitchen with a central island. Carefully designed by the current owners, this sleek kitchen design offers an expansive counter space and bountiful storage, including two appliances garages and a wine refrigerator. A suite of stainless steel appliances, including a built-in microwave, nicely contrasts white cabinetry and polished white marble countertops and backsplashes.

The kitchen flows nicely into a bright, north-facing living room, with large triple-glazed tilt-and-turn windows facing Union Street. Connected to the living area is a spacious dining room, also with views into the trees lining this historic block. The dining room, capable of seating at least six, is bookended by a beautiful custom walnut breakfront/bar cabinet, adding a focal point and extra storage to the dining space.
In the future, a new owner may choose to revert this apartment back into a three-bedroom configuration by converting the dining room into a spacious and bright bedroom.

The primary bedroom can accommodate a king sized bed and neatly hides a massive wall of custom built closets, designed by the current owners. To sleep late and stave off the southern sunlight in the bedroom, there are blackout shades installed. A second bedroom, located nearer to the entrance, currently hosts a custom built-in desk and work station, along with additional closet space. A stylish windowed bathroom includes a stall shower and custom marble vanity with warm wood tones from this custom millwork.

The location within Carroll Gardens location is hard to beat. Enjoy the serenity of bucolic Union Street, but with proximity to a thriving and exciting restaurant district, with choices nearby like Caf Spaghetti, Lucali, Swoony's, Untable, Gus's, and many, many more.

370 Union Street is located just a block from the F and G subway lines at Carroll Street. Also located just a block away is the quaint Carroll Park, and Prospect Park is just a few subway stops away.
